Abstract
Afin de réduire l'importance d'un rayonnement de dispersion éventuel dans le faisceau de mesure lors de l'emploi d'un tube de Röntgen, la face, orientée vers l'intérieur, des parties situées près de l'anode et près de la fenêtre d'entrée, est munie d'un revêtement de blindage, en particulier un revêtement d'aluminium. A cet effet, tant le corps d'anode qu'une douille anodique se raccordant à ce corps sont réalisés par exemple en aluminium. Pour établir le blindage contre des champs magnétiques perturbateurs, il est intéressant que du côté de la cathode, un matériau ferromagéntique soit incorporé à la douille anodique. Application à appareillage radioscopique utilisé en medecine.
